Hindu and Muslim marriages differ fundamentally in their nature, objectives, and rules. The main distinctions are: 
    
 Nature of Marriage:
    
        
 Hindu Marriage: It is traditionally regarded as a \textit{sacrament} (samskara), a sacred and indissoluble religious duty that binds the couple for life and beyond. 
        
 Muslim Marriage (Nikah): It is considered a \textit{civil contract} (mu'amala). It is a legal agreement between the bride and groom, requiring offer (ijab), acceptance (qabul), and consideration (mahr). 
    
    
 Dissolution of Marriage:
    
        
 Hindu Marriage: Traditionally, divorce was not permitted. It was legalized only through the Hindu Marriage Act, 1955. 
        
 Muslim Marriage: Divorce has always been permitted and can be initiated by the husband (Talaq), wife (Khula), or by mutual consent (Mubarat). 
    
    
 Marriage Rules:
    
        
 Hindu Marriage: It is governed by rules of exogamy (marrying outside one's Gotra and Sapinda) and endogamy (marrying within one's Jati). 
        
 Muslim Marriage: It is largely endogamous. It permits parallel and cross-cousin marriages, which are prohibited in Hindu custom. 
    
    
 Polygamy:
    
        
 Hindu Marriage: Monogamy is the rule. Polygamy is a criminal offense under the Hindu Marriage Act. 
        
 Muslim Marriage: Limited polygyny is permitted, allowing a man to have up to four wives at the same time, subject to certain conditions.
